In this paper, different kinds of optical performance monitoring (OPM) techniques, in particular the optical signal-tonoise ratio (OSNR) monitoring and chromatic dispersion (CD) monitoring, are reviewed. Then recent trend of multipleparameter simultaneous monitoring is examined.

We review some of the recent developments of optical performance monitoring (OPM) in various aspects: (i) the enhancement of monitoring resolution, (ii) multi-impairment monitoring, and (iii) OPM network optimization. In particular, some of the studies on the optimization of performance monitoring networks to achieve the optimal monitoring locations and the number of monitoring probes are discu...

In today's business environment in which coordination and adaptation with constant changes are the only ways of survival, real-time monitoring of activities and making the decisions accordingly are necessary. Since performance measurement cannot be managed independent of business processes, Business Activity Monitoring (BAM) systems should monitor performance metrics based on business processes...

Using path analytic-techniques, the causal relationships in Bandura's model of self-efficacy were examined in a field setting. Male intercollegiate and interscholastic baseball players (N = 53) completed self-report measures over a nine-game period during the baseball season. Perceptions of self-efficacy, competitive state anxiety, effort expenditure, and objective hitting performance were meas...
